Get a voiceover read that actually matches your video's pacing, not a generic narrator drone

Why this works

Most voiceover prompts fail because they describe a voice in the abstract ("professional, friendly") without tying it to the actual pacing constraints of the video it sits under, so Voice Design defaults to an even, generic narrator cadence that doesn't match where a viewer's attention actually needs to land. Naming a specific word or phrase for emphasis works because it gives the model a concrete acoustic target — a stressed syllable and a slight pitch rise on one word — rather than a vague instruction like "emphasize the important parts," which Voice Design has no way to act on since it doesn't know which parts you consider important. The explicit pause-point field matters even more for UI walkthroughs specifically: a beat of silence right before an instruction like "click Save" gives the viewer's eyes time to find the button on screen, and that timing gap is exactly the kind of structural cue Voice Design will reliably insert when told where to put it but will never invent unprompted. Tying the pacing note to the edit itself ("slightly slower... so viewers can follow along with each screen change") rather than a generic speed adjective is what keeps the narration in sync with a video that has hard cuts on specific actions.
